2. Coughing up blood is another sign you have tuberculosis.
When you cough for a long period of time, blood will come up. A lot of times, when the blood vessels are unable to flow properly through the body, it has to come out some kind of way. The infection as a spread and the only way to get rid of it is with antibiotics. People already with an infectious disease, such as HIV, may cough up blood. The person needs to seek medical treatment right away because after awhile it may cause the person to cough up blood uncontrollably.
Sometimes a person can choke on their own blood and can lead to death. It is a serious condition and needs to be taken care of immediately. The coughing of blood should cease once the person gets antibiotics in his or her body. When coughing up blood, it can spread easier too.
